. To all whom itrnd concem;

Be it known t at I, JQEN'D. Kenna, a citizen of the United States,residing f at Roselle Park, in the. coui1ty of'Uni'on and, State of NewJerse have invented certain new anduse ul Improvements in Latches, ofwhichthe .followmg is a specifi cation, reference being had therein to.the accompanying drawings. 4

This invention relatesto-a latching def vice f or separably securing twopartsl of a container such as a portable casing for sew machines and thelike;

in v. t aims to provides new and i m'provedaccess for manipulation isprovided by a counters'unk'opening in oneoi the two sap-- arable partsof the container on whicht e mounted. y

Other objects of theinventionvwill ap' ear. in the following detaileddescription 0 the accompanying drawings, in which Fig. 1' represents oneform of the invention in per-- spective. Fig. 2 represents across-section v on line ob,Fig. 1, looking in the direction indicated bythe arrows. Figs. 3 and g 4-; represent in plan view a modifiedconstruction for the manipulating ends of the lever in non-registeringand registering position, respectlvely'. Fig. 5 re resents across-section on the lines a-d, F1 3, looking in the direction indicatedby t e arrows.- Fig. 6 represents the form of key that may be emplo edto o erate the manipulatin ends oi t e levers In their form illustratein Figs. 3, 4 and 5.
